please help me quickly I will vote your answer with high rate 9Part 1In the Lecture related to the subject Binary search Trees, we have looked atthe Algorithm proper to In-order Tree walk, this algorithm is so namedbecause it prints the key of the root of a subtree between printing thevalues in its left subtree and printing those in its right subtree, we haveillustrated it by an example to print the node's keys in a monotonicallyincreasing order.Similarly, a preorder tree walk prints the root before the values in eithersubtree, and a postorder tree walk prints the root after the values in itssubtree.Questions:1.Write down the recursive algorithms that perform preorder andpostorder tree walks on a tree of nodes.2.15Apply in-order, preorder and postorde, tree walk on the followingBinary search TreePart 2172023272930364049557175We have studied as well the Algorithm Tree- Successor that looks for theSuccessor of a given node, Write down the Algorithm for Tree-predecessor that looks for the predecessor of a given node, use the fact thattree-predecessor is symmetric to tree- successor to help you in writingdown your solution.95

Use the recursive strategy described in the chapter to implement a binary tree. Each node in this method is a binary tree. Thus, a binary tree includes references to its left and right subtrees in addition to the element stored at its root. You could also wish to make mention of its progenitor.

} 20. In a binary search tree, the immediate predecessor of a given node is the largest node in its left subtree. For example, the immediate predecessor of node 25 in the following tree is 23 while it is 15 for node 16. Nodes 21 and 39 do not have an immediate predecessor because none of them has a left child. 25 / 1 Write a non-recursive method immediate Predecessor, which takes a BSTNode parameter node (a reference to a node in a binary search tree) and returns a reference to its immediate predecessor in the tree.

Problem Description Using the binary search tree (BST) data structure, we can sort a sequence of n elements by first calling an insertion procedure for n times to maintain a BST, and then performing an INORDER-TREE-WALK on the BST to output the elements in sorted order. To insert a node, we've discussed the TREE-INSERT procedure in class (also from page 294 of the text- book). This TREE-INSERT procedure can actually be improved to reduce the number of key comparisons so that each node's key is compared with the new node's key for at most once during each insertion. For example, given the following BST, The improved insertion procedure will make • 2 comparisons to insert a node with key = 1 • 3 comparisons to insert a node with key = 3 • 2 comparisons to insert a node with key = 8 5. Program Requirements In this programming assignment, you will implement in Java this sorting algorithm using BST, by using the improved insertion procedure. Note that each node of a BST is an object…

9. A binary tree is symmetric if for every internal node the number of nodes in its left subtree is the same as the number of nodes in its right subtree. Given a node p, let p.size() return the number of nodes in the subtree with root p, and p.getLeftChild() and p.getRight Child() return the left and right children of p, respectively. Write a recursive algorithm public boolean isSymmetric (Binary TreeNode r) that receives as parameter the root r of a binary tree and it returns true if the tree is symmetric and it returns false otherwise. For example for the tree below with root r the algorithm must return true, but for the tree with root s it must return false. $8,89 Figure 3
